Can anyone with past experience, who invited their parents over to the US to see a newly born please share what documents are needed to show to the US embassy? How do I write a letter to the US embassy, what would be the best way to describe why I want to have my parents over during this special occasion? I don't want to say I need my parents over to take care of the little one, as they might think I am inviting them for babysitting work. Would cultural or religious reason be a better approach, like I need elderly people to bless the child during 'Nwaran' ceremony, or presence of someone elderly during the time of birth would be helpful as they have the knowledge and experience than me, who is having a kid for the first time? What do you guys think? Please share your thoughts and experiences. Would mean a lot for me!

Also what documents do I need to send to Nepal from here, before my parents apply for the visa at the embassy?
Thanks to the folks, who took time to read this and took a moment out of their life to share their experiences.
